TUBE AMPS 101 or Things I Wish Someone Had Told Me When I Started - DVD
Over 1 ½" hours of video that is like standing over the shoulder of an amp tech for a day, minus the technical jargon. Learn all kinds of tips and tricks, while you watch from your easy chair. This video focuses on an amp that is presented as a 1964 Fender Deluxe Reverb and shows you how to determine its exact date of manufacture. While you go through the test amp you are shown all the things to look for in rehabilitating an old amplifier, things like seeing if the caps are bad and replacing resistors.

This is the book that jump-started the boutique tube guitar amp business. Learn the truth about tube preamp design and modification; see how tube power amps work and can be made more reliable; see how reverbs and effects loops work and better ways to configure them; learn why some amp brands are easier to service and to mod than others; see how simple switching circuits are but how capable they can be. Tube data for the common types used in guitar and bass amps is provided, along with a discussion of stage set-up and player ergonomics.

Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn't change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the "iconic" amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product.

London Power DIY Speaker Cabinets for Musical Instrument Applications. Speaker cabinet design is mysterious to most people, but it doesn't have to be - especially when it comes to speakers for musical instruments. Cabinet evolution is described culminating in Kevin's own designs built by London Power, based on 20+ years of experience and input from expert speaker designers. Resonant and non-resonant cabinets are explored, along with the choice for building materials, finishes, woodworking techniques, installing grill cloth, and the use of wheels and handles. Driver selection and mixing is detailed, covering driver impedance, power ratings and wiring.

Every part of your system contributes to your Ultimate Tone, so every part is important. TUT5 delineates, in clear language, the function of each electronic component in a circuit, and how alterations to the value of each part affect the final sound. Gain stage voicing, interstage attenuator optimization, sustain restoration for clean and distorted tones, power amp and preamp "tone generators", simple boost pedals, amp selectors and power conditioners are all covered, with designs using off-the-shelf parts.

Outlines, in schematic form, many approaches that achieve the goal of power scaling, super scaling and power management. A complete history and discourse on the technology outlines how to implement multiple power scale controls, alternative circuit forms and system impacts. Further tutorials outline the methods for super scaling, with both fixed and variable boost ratios, using both solid-state and tube methods.
